Comparisons like this sorely tempt me to quote Bryant Gumbel, but instead I will just point out that if my stereo were built into my refrigerator, I bet that it would sound so much better, if I got in and closed the door, because with all that insulation, it would be almost soundproof, so I could turn it up without disturbing the neighbors, and I heard that sound travels faster through cold air, so that's got to be better! Put a handle inside, and wearing scuba gear so I could listen to a whole CD without suffocating, and WoW! what a fine sound machine that would be! And my car, you know, it would make a much better Space Shuttle than the real one, cause the windows to surface area ratio is many times more than the NASA version. So if I could seal it really well, and get some solid rocket boosters, and put some heat-resistant paint on for re-enty, I think it would be much cooler, since it handles much better than NASA's, except maybe on ice. And if Amir would just copy DJ's code to 480 specially designed chess proceesors attached to 30 IBM SPs in two helium-cooled towers, I would gladly trade him an awesome concert emulator and a space shuttle for it! kp
